Table of signs of malfunction (Freelander 2)

Sign of malfunction	Possible reason	Action
The engine turns over but does not start	Low fuel level/contamination Leak in the air intake Fuel system leak, blockage/clogging Electronic engine controls	Check for low/contaminated fuel Check the integrity of the air intake system Check the fuel system for leaks and blockages/restrictions. Read the DTCs and refer to the appropriate DTC Index For Electronic Engine Controls Tests For additional information, refer to: Electronic Engine Controls (303-14, Diagnostics and Testing).
Difficulty starting	Glow plug malfunction Low fuel level/contamination Check the coolant level/antifreeze concentration in the cooling system Battery Leak in the air intake system Electronic engine controls Leak in the injector Fuel system leak, blockage/clogging	Check the integrity of the glow plug system Check for low/contaminated fuel Check the coolant level and condition. For more information, refer to: Specifications (303-03B Engine Cooling - 2.2L Duratorq - Td4, Specifications). Make sure the battery is fully charged and in good condition Check the air intake system for leaks For Electronic Engine Controls Tests For additional information, refer to: Electronic Engine Controls (303-14, Diagnostics and Testing). Check the injectors for leaks, install new injectors if necessary. For more information, refer to: Fuel Injector (303-04B Fuel Delivery and Controls - 2.2L Duratorq - Td4, Removal and Installation). Check the fuel system for leaks and blockages/restrictions. Read the DTCs and refer to the appropriate DTC Index
Rough idle operation	Leak in the air intake system Low fuel level/contamination Fuel system leak, blockage/clogging EGR valve malfunction	Check the air intake system for leaks Check for low/contaminated fuel Check the fuel system for leaks and blockages/restrictions. Read the DTCs and refer to the appropriate DTC Index Check the EGR system for proper operation. For more information, refer to: Emission Control (303-08B Emission Control - 2.2L Duratorq - Td4, Diagnostics and Testing)
Engine lag/poor acceleration	Leak in the air intake system Clogged exhaust system Fuel system leak, blockage/clogging EGR valve malfunction Turbocharger actuator failure	Check the air intake system for leaks Check the exhaust system for blockages/obstructions Check the fuel system for leaks and blockages/restrictions. Read the DTCs and refer to the appropriate DTC Index Check the EGR system for proper operation. For more information, refer to: Emission Control (303-08B Emission Control - 2.2L Duratorq - Td4, Diagnostics and Testing). Check the turbocharger actuator for proper operation. Read the DTCs and refer to the appropriate DTC Index
Engine stops/stalls	Disconnection/reduction of ventilation system capacity Leak/blockage in the air intake system Electronic engine controls Fuel system leak, blockage/clogging EGR valve malfunction	Make sure that the engine crankcase ventilation system does not have a reduction in flow capacity and is installed correctly Check the air intake system for leaks/blockages For Electronic Engine Controls Tests For additional information, refer to: Electronic Controls (303-14B Electronic Controls - 2.2L Duratorq - Td4, Diagnostics and Tests). Check the fuel system for leaks and blockages/restrictions. Read the DTCs and refer to the appropriate DTC Index Check the EGR system for proper operation. For more information, refer to: Emission Control (303-08B Emission Control - 2.2L Duratorq - Td4, Diagnostics and Testing).
Excessive fuel consumption	Fuel pressure, fuel pump, fuel line blockages/contamination/leaks Leak in the injector Electronic engine controls EGR valve malfunction	Check fuel lines for leaks and blockages/restrictions. To test the fuel pump, check for DTCs and refer to the appropriate DTC Index Check the fuel injectors for leaks and install new injectors if necessary. For more information, refer to: Fuel Injector (303-04B Fuel Delivery and Controls - 2.2L Duratorq - Td4, Removal and Installation). For Electronic Engine Controls Tests For additional information, refer to: Electronic Engine Controls (303-14, Diagnostics and Testing). Check the EGR system for proper operation. For more information, refer to: Emission Control (303-08B Emission Control - 2.2L Duratorq - Td4, Diagnostics and Testing).
